I hate to say it...but!
From my experience and LOTS of money spent, I wouldn't drop another nickel on any 4.6L engine.
(Terminator Cobra motor is the ONLY 4.6L worth a nickel....and note; it is bulletproof from the factory AND it has a blower bolted onto it....and I still wouldn't buy one.)
Coyote 5.0 FTW!!
....or stick with the unmodded, big, overweight, complex, underpowered turd 4.6L.
I was a HUGE fan of the 4.6L DOHC when the Marauder debuted....
19 years ago.
Technology advances and the 4.6L has been left behind.
5.0 Coyotes are making 480HP....N/A
Better flowing heads
Bigger valves
Better spring package
Better intake manifold
Better camshafts
Variable valve timing
Higher compression ratio
Port and Direct FI
Forged crank
Stronger rods
Stronger pistons
Better aluminum block
+ 178 HP
+ 102 Lb-Ft TRQ
Better fuel mileage too!
Junkyard F150 Coyote is also a nice option.
